• Class: attested
• The single codeword is supported by the codewords confirming CRC-6/DARC, defined identically apart from Width, Poly in the same standard. The source presents the codeword in transmission order, whereas the codeword is composed of the bytes of data sent LSB first. The example input message is 190 bits long, considering that the inner CRC is 14 bits. The CRC mask is …C0 FF FF FF FF FF FF FF FF FF FF.
